7 Claims (o1. 454584) Our invention relates to devices for protecting.office machines, such as typewriters, adding machines, accountingmachines, calculating niaohines, and other similar machines, from thedust .5 when not in use.

1 ,Ihe objects of our invention are to. provide such a covenfirst, as.will be out of. sight and out of the way when it is not in use; second,as will take up very little room when not-in use;

third, which may be incorporated .as a partnof the machine or which maybe attached to :a machine; fourth, which folds up automaticallywhenremoved from operative position and which rolls up automatically andsmoothly out of the way, when so folded; and fifth, which is simple tomake, easy. to attach to a machine and to operate, and effective in use.

W e attain these and other obj ects,.such as appear from thedescription, by the devics'mechcompanying drawings, in which- Fig. 1 isa side elevation of a machine showing our invention applied thereto androlled away to permit the free use of the machine; Fig. 2 is .a similarView showing our improved cover being unrolled from said stowed awaycpndition; 3

is a similar View showing our improved cover fully applied to cover themachine; Fig. 4 is a front elevation {of the machinewhenso covered; 7Fig. 5 is a side elevation, partly in section, showing the container forour improved cover; Fig. :6 is a rear elevation of one end thereof; Fig.fllisxa plan view of our improved cover before it is folded and appliedto the roller, and showing the lines on which it is to be folded andsewed; Fig. 8 is aside elevation of our improved cover folded-and'sewedand applied to spring roller; Fig. 9 is a top plan View thereof; andFig. 10 is a diagrammatic end elevation of our improved cover to showthe manner and form of its folding.

Similar numerals of reference refer to similar parts throughout theseveral views.

Our invention is illustrated as applied to a typewriter but it is to beunderstood that, with appropriate changes in dimensions, the cover maybe applied to any desired device or machine, such as those indicated inthe above general statement. Also, the form illustrated is that in whichthe cover and its container are secured to such a machine as alreadymade, but it is to be understood that the roller on which the cover ismounted may be permanently incorporated within the frame of the machine,the cover emerging therefrom through a suitable slot, or the containermay be a permanent part of the machine.

anisms and arrangements illustrated in theac fl now to the drawings, themachine frame I is mounted on suitable cushioned legs 2. Acvertica'lfastener plate 3, having horizontal fastoning armed, which aneadapted to be secured in place between the frame 4 and the said legs 2,extends across the machine 4. Thisplate .3 is substantially as long asthe width of the machine frame land is positioned at the rear thereof ona level with the base thereof. A vertical carrier plate 5 is secured tothe fastening plate 8 :bymeans of suitable bolts ii. In some cases theoonstmmtion of the frame 1 is such that the carrier plate 5 may be.secured directly to the rear of the said frame 4 using the fasteningplate Theoarnier plate 55 is provided with two cars .1, one at each end,extending rearwardly therefnom andslmpcd substantially as shown in thednawines. ears i are provided with suit able :beaaing lmies 18 adaptedto receive and support the end trunnions of a suitable spring roller ,9.The hollow spring roller 9 is not illustrated in detail since-it .of thewelieknown type and of the usual construction, having one trunnionioumaled in one ear 1 and having an helical spring H) mountedlwithin it,said spring being attached at its inner end to the said roller 19 and atits ntherend to the other trunnion, which is held from rotation by theother ear 1. of .the container. The seller is also provided withsuitable holding dogs, not shown, mounted in the usual ,wayto preventits undesired rotation. Aaneta'l cover 1! lies on theloutsideledges .ofthe .ears 1 and is provided with suitable clips 12 adapted to hold it inplace and to stiffen the ears '1 laterally, said clips the removal .ofthe cover M when desired. The cover li ieanes .a. space 13 between theframe I and theupper edgelof the metal comer, forming aslot throughwhich our improved machine compasses to or from the spring-roller 9, onwhich it is rolled.

' Our improved typewriter cover is made of suitable cloth or fabric andis cut substantially as shown in Fig. 7. The central part 14, betweenthe two lines 15, is slightly narrower than the. width of the machine tobe covered, and is pro vided with a tail IQ, of the same width, which isadapted to be secured to the outside of the spring roller 9. A pleat isformed on each side of the central part l4 by creases made on thecorresponding lines I! and H3.v The side panels I9 extend from the foldsH! to the side folds 29, a distance substantially equal to one-half ofthe width of the central part l4, and are adapted to lie immediatelyunder the said central part 14 (Fig. 10). The edge Zl'is about the samewidth top 'of the ears of the container.

as either of the two elements of the pleats. The width of the pleatelements between the creases I5 and I1, and I1 and I8 will vary withtheparticular machine to be covered. 7

When the cloth has been cut and. folded as 'above described, the rear orinner end is sewed byagrowfof stitching on'the line 22, thus securingall the parts together in front of the tail l6. Similarly the front orouter end of the cover is turned over a rod 23 'andis stitched on theline 24, thus securing the rod to the cover and securing all the partstogether along the front line. 'The rod 23 islonger than the width ofthe central part M of the cover and extendslout on each side.

thereof when sewed in place. 7 u 7 The operation of our improved machinecover is briefly as follows-It is noted that in Fig. 1

roller 9 catches and prevents its being further drawn back; then therod23 is carried forward over the machine and allowed torest in frontthereof; then the sides, which lie under the cover thusplaced, are drawnout laterally and draped over the parts of the machine extendingoutbeyond the sides of the frame I; .In this position it will be notedthat, though the side strips 20 and 2| have a shorter distance to passfrom the rear to the, front, they actually passabout as far as thecentral part 14 because the sewing seams 22 and 24 attach said part tothe center part I, and while the said center part I4 passes over the topof'the machine, the said sides pass from the center of the rear aroundthe side to thecenter of the front of the machine.

.Now, when it is desired'to stow the cover away, all that it isnecessary to do isto raise the stiffening rod .23 vertically and thesides of the cover will pull away from the machine and, at once, andautomatically, will assume their proper positions for being rolled (Fig.2) and then, by pulling upward on the said rod 23 to release the rollerdog, the entire cover will 'be withdrawn into the container bybeingrolled neatly on the said spring roller. We have found that, byfolding the cover in the manner above described, it will pass on to theroller without buncliing or unnecessary wrinkling. r

It is to be understood that many variations may be made in theembodiment of our invention without departing from the spirit thereof asoutlined in the appended claims.-

Having described our invention, what we claim and desire to secure byLetters Patent, is:-

1. A roll cover for machines comprising a spring roller mounted on the,rear of the machine; a cloth cover secured to said spring roller and ofwidth greater than the width of said roller and folded in on itselfbetween its ends, said folds being secured together at its ends; andstiffening means extending across the outer end of said cover.

2. A roll cover for machines as .set forth in 2 claim 1, wherein saidcloth coveris pleated at its folded edges.

3. A roll cover for machines comprising a spring roller mounted on therear of the mapanels, with pleats folded between the side panels and thecenter portion; and stiffening means extending across the outer end ofsaid cover.

4. A roll cover for machines as set forth in claim 3, wherein the sidepanels extend from the pleats substantially to the center of the centerpart of thecover, and on the underside thereof.

5. A roll cover for machines as set forth in claim 3, wherein saidclothcover is of a width greater than twice the width of said roller, and theside panels extend from the pleats substan tially to the center of thecenter part of thecover, and on the under side thereof.

6. 'A roll cover for machines, comprising a carrier plate secured to therear of the machine; a pair of ears extending rearward fromthe ends ofsaid carrier plate; a metal cover mounted on said ears and formingtherewith a container; a spring roller mounted between said ears and inthe container; a cloth cover secured to said spring roller and of awidth greater than the width of said roll: er and folded in on itselfbetween its ends, said 'ends being sewed in folded condition; and a rodsewed into the outer end of said cover and extending beyond its foldededges.

'7. A roll cover for machines, comprising a fastener plate secured tothe rear legs of the machine; a carrier plate secured to said fastenerplate; a pair of cars extending rearward from the ends of said carrierplate; a metal cover mounted on said ears and forming therewith acontainer; a spring roller mounted between said ears and in thecontainer; a cloth cover for the machine secured to said spring rollerand of width great er than twice the width of said roller andfolded inon itself between its ends, said ends being sewed in folded condition;and a rod sewed into the outer end of said cover and extending beyondits folded edges.
